Abstract (en)
[origin: EP3770521A1] An air conditioning system includes: outdoor units (2-1 to 2-3); indoor units (1) each communicating with any one of the outdoor units (2-1 to 2-3) by a first communication method; and a central control device (3) communicating with each of the outdoor units (2-1 to 2-3) by a second communication method and controlling the outdoor units (2-1 to 2-3) and the indoor units (1). One of the outdoor units (2-1 to 2-3) generates, by using a first address used for communication performed using the first communication method, a second address used for communication performed using a second communication method, generates a second address for one or more of the indoor units (1) by using a first address, and obtains second addresses from another outdoor unit and the central control device (3). The central control device (3) obtains, from each of the outdoor units (2-1 to 2-3), second addresses of the outdoor unit and each indoor unit, and controls operations of the outdoor units (2-1 to 2-3) and the indoor units (1) by using the second addresses obtained.
